This 64GB DDR4-2400 RDIMM with ECC is a server-grade module purpose-built for virtualization, in-memory databases, and data-critical enterprise workloads. Its Quad Rank x4 organization maximizes capacity per channel while the registered signal topology and CL17 latency maintain rock-solid stability under heavy, multi-threaded loads.
1. Registered RDIMM buffering stabilizes signal integrity across fully populated server boards, preventing data corruption in large-scale virtualization clusters.
2. ECC error correction catches and fixes single-bit memory faults in real time, safeguarding transactional databases and long-running analytics workloads.
3. Quad Rank x4 organization delivers massive capacity per channel while keeping memory buses saturated, essential for hosting dense VMs without bandwidth starvation.
4. 64 GB capacity per module allows a single 1U server to host hundreds of containers, maximizing consolidation ratios without sacrificing compute headroom.
5. 1.2 V DDR4 operating voltage reduces thermal stress in rack-dense deployments, lowering cooling costs and improving long-term hardware reliability.
When deploying mission-critical server infrastructure, the M386A8K40BM1-CRC40—a 64GB DDR4-2400 Registered ECC RDIMM—becomes the silent guarantor of uptime and data fidelity. Its ECC engine corrects single-bit errors on the fly, which is non-negotiable for an in-memory database like SAP HANA; a silent bit-flip in financial transactions can corrupt a multi-billion-dollar ledger without warning. The Registered buffer isolates the memory controller from excessive electrical load, so you can fully populate all 24 DIMM slots in a virtualization host without sacrificing signal integrity. For you, that means a dense VMware or Hyper-V cluster can reliably run dozens of latency-sensitive VMs side by side. At 64GB per stick, this quad-rank x4 module lets you pack massive capacity—easily reaching 1.5TB in a dual-socket server—to keep increasing active datasets entirely in DRAM. The quad-rank interleaving also sustains high bandwidth under heavy concurrent access, translating directly to faster query responses in large-scale analytics and smoother VDI sessions during peak hours.
General Virtualization
For a DDR4-2400 Registered ECC module, populate balanced channels to maximize memory bandwidth under mixed VM workloads. Deploy six or eight identical 64GB RDIMMs in a dual-socket server (one DIMM per channel) to reach 384–512 GB, ensuring ample headroom for memory overcommitment while preserving NUMA locality.
In-Memory Database
Low latency and data integrity are paramount; use a fully symmetric configuration with one quad-rank 64GB RDIMM per memory channel to avoid rank contention. In a typical two-socket system, install 12–16 modules for 768 GB–1 TB capacity, and set the BIOS to maximum reliability mode to leverage ECC scrubbing and patrol functions.
High-Performance Computing
HPC nodes benefit from balanced memory interleaving; configure identical 64GB Registered DIMMs across all populated channels (e.g., six or eight per socket) to sustain 2400 MT/s at CL17. This delivers up to 1 TB per node, reduces memory wall effects in parallel job scheduling, and the quad-rank design keeps per-socket bandwidth high.

Q: Can I mix this M386A8K40BM1-CRC40 with other memory modules of different brands or speeds?
A: Mixing is not recommended. Inconsistent ranks, speeds, or timings can cause instability or prevent booting. For reliable ECC operation and quad-rank architecture, always use identical M386A8K40BM1-CRC40 modules.
Q: Is this memory compatible with my system?
A: This 64GB DDR4-2400 RDIMM is designed for Intel Xeon E5-2600 v3/v4 and AMD EPYC 7001 series platforms. Verify your server board supports registered ECC modules and quad-rank 288-pin DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules per channel, starting with the blue slots (often channel A1, B1). For quad-rank DIMMs, avoid mixing ranks within a channel and follow your server board’s memory configuration guide precisely.
Q: Does this module support overclocking or XMP profiles?
A: No. As a registered server memory module, it adheres to strict JEDEC DDR4-2400 standards. XMP and overclocking are disabled to ensure mission-critical data integrity and ECC functionality.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Enterprise-grade RDIMMs with ECC typically demonstrate very low failure rates, especially when operated within specified voltage and thermal limits.
